IMPROVEMENT IN STEAM WATER-EJEGTGRS.

"dlp tlgetule aient ltf1 im:l tigen? g'tttttts rtntt :uit uniting pitt nt tip stmt.'

TO ALL vWHOll/IZIT MAY CONCERN:

13e it known that I, H. SCHUYLER Ross, of NewYork city, in the county Sand State ot' New York, at present in the Engineer Corps of the United States Navy, have invented new and useful Improvements in Steam Water-E ieetors; and 1 dohereby .declare that the following is a full, clear, and exact description of the same. reference being hadto the accompanying drawing, forming part' of` this speciiication. Y

This invention consists in the combination, withan auxiliary receiving-pipe in steam waterejectors,of an annular or surrounding steam-way or nozzle, so arranged relatively to each other, that the steam employed for iforcin'g forward the-water will n ot,only act upon the water rising in the auxiliary receiving-pipe, but also upon the water in a surrounding pipe or reservoir; it also consists in such construction of the nozzle steampipc or way that the same, when forced forward or backward, orby other movement, will regulate or entirely cut oii` the dow of steam'therefrom, whereby `a great saving in steam is eifected'.

In the acceuipany'ingdrawing;u

Figure 1 is a longitudinal central section of my invention.

Figure 2 is a similar view of my invention applied to a. style of ejector `new in use.

Figure 8 is a similar view of my invention,considerably enlarged.

A, (refer to hg. 1,) designates the discharge-pipe, and B the suction-pipe, the latter branching oii' from the former, and describing something of an angle therewith.-

C designates a steam-way or nozzle, which, in the present instance, is let into the force-pipe A, at the angle formed by it and the suction-pipe B. The walls of this nozzle are designated by letters a a, and the space within these walls is an annularsteam-chamber or way, into which steam `is conducted through a pipe, D.

E is an auxiliarysuction-pipe, whose` upper end is let into the chamber or nozzle .0. Where the pipe E enters said nozzle, I employ a. stuidngbox, to form avsteam-tight joint. This auxiliary suction-pipe is constructed and arranged so that by a longitudinal movement thereoi` the quantity of steam issuing from the steaml nozzle may be regulated as desired. screw-thread, b, cut upon` the pipe, and working in' a nut, e, is employed in the prcsentinstance, and a Wheel, d, forfturning the pipe E, in order to.`move it longitudinally.

The top edges of the walls ct, of the steam-chamber nozzle or way, are bevelled inward,. and the top edge or end of the suction-pipe Eis bevelled outward in a corresponding manner, as will be seen by reference to.

:.tg. 1. Now, by forcing the suction-pipe E upward, till it strikes the bevelled top edge of the walls a a, the

ilow of steam will 'be entirely cut oil. It is therefore evident that the quantity of steam allowed to issue from the nozzle C can be regulated as desired, by merely throwing up or down the suction-pipe E In iig. 2, substantially the same kind ot a steam water-ejector is shown, exceptthat the force-pipe A has two suction-pipes, vl? B.v In this example, as will be seen plainly in Vthe enlarged view, iig. 3, the top end ofV the suction-pipe E is bent inward, and the upper end of the nozzle corresponds therewith, and the ow of the4 steam is regulated by a longitudinalmovement ofthe suction-pipe E, as before described.

I will horeremark, that the tops of the auxiliary suction-pipe and the steam-nozzle, may be constructed 'in various Ways, so as to enable' the regularity of the ilow of steam, and I dc not therefore limit myself to the construction as herein shown. i

A lining or coating, ot' felt, e, hg. 3, or other non-conductor of heat, is placed upon the surface of the steam-nozzle pipe or way, where it is exposed to the 'water'. A similar' lining or coating, j', may also be employed upon the inner surface of the auxiliary suetionfpipe. By the employment ot" such lining or coating in combination with such exposed surfaces, condensation of steamis prevented in a great degree. l

By the above improvements in steam water-ejectors, I gain many advantages, among whichvma'y be recited the economizing of steam, and the gaining of an independent 'stream of water, acted upon by thcsame steam, which forces-the water out of an ordinary steam ejector.

I am aware that in the Giard ejector a plug is used for closing, the steam-way, but I do not luse a plug, but a pipe, which in itselfserves-an important purpose, as' before recited.

e to secure by Letters Patent, is-

dnctor- E, in such relation to the steam-pipe or jet C, that pipe or jet, substantially as What I claim as my invention, and lesii;

1.l The arrangement of the water-pipe or con th'e discharge-end of such water-pipe shall open or discharge -Within the steamherein specied.

2. The arrangement of the waterwater-pipe or conductor, the How vof stezim substantially as herein specified.
